US President Donald Trump discussed some of the hot topics of the upcoming Helsinki meeting with Russia President Vladimir Putin, during a presser at the annual NATO Summit in Brussels, Thursday.

"He's a competitor. Somebody was saying, 'Is he an enemy?' He's not my enemy. 'Is he a friend?' No, I don't know him well enough but a couple of times that I've gotten to meet him, we got along very well, you saw that," said Trump, speaking of Russian President Vladimir Putin.

"He's not my enemy, and hopefully someday he maybe he'll be a friend, it could happen but I just don't know him very well; I've met him a couple of times," added Trump.
